Specification of Letters Patent.

Patented Feb. 7, 1911..

Original application filed. March 23, 1907, Serial No. 364,172. Dividedand this application filed April 14,

Serial No. 426,952.

To all whom it may concern:

Be it known that I, GiUsnPrn Rocco, a subject of the Emperor ofAustria-I-Iungary, residing at Trieste, Empire of Austria- I-Iungary,have invented certain new and useful Improvements in Intermittent-LightApparatus for Sea-Lights; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This application relates to an intermittent light apparatus for sealights and particularly to one in which acetylene is eniployed and is adivision of the application for Letters Patent filed by me on the 23rdday of March 1907, under Serial #364,172, on which Letters Patent weregranted on the 7th day of July 1908, and numbered 892,893.

I am aware that heretofore intermittent light apparatus have beenconstructed in which in a single pipe leading to the burners a valve hasbeen provided in connection with 11 cans for alternately opening andnearly but not entirely closing the said valve, whereby an intermittentlight is produced. An apparatus of this nature however, requires a veryexact adjustment of the valve in order to prevent and insure the samefrom becoming choked by dust or other impurities in the gas, or fromother reasons, any one of which is likely to render the same inoperativeand thus extinguish the light.

In carrying out my present invention, I preferably employ a wet gasmeter through which the gas in a suitable holder passes into two pipesor tubes; one of these tubes being provided with an adjustablethrottling device and the other with a valve or equivalent means foralternately opening and closing the same at predetermined intervals; thesaid pipes or tubes leading independently of one another to a pipe forsupplying the burners of the intermittent light. The throttling deviceaforesaid when placed in one of the said tubes permits a constant flowof a regulatable quantity of gas to the burners of the light; thisquantity of gas preferably being just suflicient to maintain smallflames which are not visible at any great distance, Whereas theaforesaid valve or equivalent means employed in the other tube when openpermits a relatively large quantity of gas to flow to the burners,so-that the flames of the light are increased accordingly, and when thesaid valves or equivalent means are closed, the flow of the gas throughthe said second tube is shut off and only the small flames are producedin the said burners. I also employ suitable means for automaticallyoperating the aforesaid valve to open and close the same atpredetermined intervals as will be hereinafter more particularlydescribed. In the drawing, Figure l is a side eleva tion of theapparatus comprising my present invention. Fig. 2 is a cross sectiontaken on the line :0, m, Fig. 1, passing through the axis of thependulmn, showing the left hand valve seat indicated at 6 and the tubes4 and 5 removed for the purpose of more clearly illustrating theconstructionof the apparatus; and Fig. 3 is an enlarged front elevationshowing the entire apparatus in which my present invention is included.

Referring particularly to the drawing, 2 designates a wet gas meter towhich through a suitable pipe 1 the gas employed to light the burnerspasses from a generator orholder, which latter is not shown; the flow ofthe to the said wet gas meter being controlled by a valve indicated ata. From the wet gas meter the gas passes by two independent paths to theburners at which the same is ignited. One of these paths comprises thetube 3 and the other path comprises the tubes 4 5 between which there isplaced a valve, the seats of which are indicated at 6 receiving betweenthem the rocker valve indicated at 7. The tube 5 is preferably providedwitha valve (Z for con trolling the passa e of the gas and this tube aswell as the tube 3 communicate with the burners indicated at 5 In thetube 3 I preferably employ a throttling device indicated at 3 Thisthrottling device may be a valve of any well known construction or othermeans by which a regulatable quantity of gas may pass from the meter tothe burner; the quantity of gas being just sufficient to maintain thesmall flames in the burner which are not visible at any great distance.On the other hand, as hereinbefore described, between the tubes 4: and 5there is a valve or other device which as shown may comprise a valvehaving seats 6 similar in every respect and slightly spaced apart fromone another; the tube 4 being connected to one side of one 01'' thesevalve seats and to the opposite side of the other of said valve seats.This latter tube connects with the tube Between the valve seats 6 Iemploy a rocker-valve 7 having an opening 9 therein adapted in oneposition of the valve to register with the ports 10 in the valve seats6, and in the other position of the valve to close the said ports 10thereby permitting the gas to flow freely through the tube t or tocompletely shut oil the flow of the gas through this tube 4. Thisrocker-valve 7 is preferably journaled as indicated at 11 in the valveseats 6 and has secured thereto an arm 12 in the outer end of which issecured a rod 0. The arm 12 and consequently the rocker-valve 7 areacted on by a spring 13 to maintain the same in a normal initialposition.

The rod 6 is provided with a dog 1% adapted to bear against the teethprovided in the periphery of a wheel 15 which is mounted in a suitablearbor and driven by a worm 17 and worm-wheel 20, and the turning of thisarbor is controlled by a clockwork having the usual pendulum 16 adaptedto swing on an arbor 9 provided with the usual escapement 71. providedwith a toothed wheel 2' and pinion 7c and an arbor Z, the pinion 70meshing with the toothed wheel m which is mounted on the arbor 19; thearbor 19 being coupled to the arbor 18 on which the worm 17 is mounted.The arbor 18 is connected to and turned by the registering mechanism ofthe gas meter 2.

It will be apparent that in the turning of the wheel 15 that the teethon the periphery thereof will successively come under and raise the dog1% on the free end of the rod 0, thus actuating the rocker-valve 7againstthe action of the spring 13 and that when the rocker-valve isbrought into the position shown in Fig. 2, the passage of the gasthrough the tube 4: is shut off, and when one of the teeth of the wheel15 has passed beyond the dog lt on the free end of the rod 6 therocker-valve will be actuated by a spring 13 and moved to the positionshown in dotted lines Fig. 2, wherein the port in the rocker-valvecoincides with the ports in the valve seats, thereby permitting the gasto flow freely through the tube L and thence pass to the burners; itbeing readily apparent that the regularity of the intermittent light isobtained by and through the gas cooperation of the clock-work with themeter.

I claim as my invention:

1. In acetylene lighting apparatus the combination with a gas meter andburners, of two tubes communicating at one end with the gas meter and atthe other with the burners, means for regulating the passage of the gasthrough one of said tubes, two valve seats parallel to and opposite eachother and placed in the other of the said tubes whereby said other tubeis divided into two parts, the said valve seats being provided withports opposite each other and each communicating with one of the partsof said other tube, a rocker-valve adapted to move between and incontact with said valve seats, the said rocker-valve having a porttherein adapted to be moved into and out of line with the ports in bothvalve seats, and means for actuating said rocker valve, substantiallyand for the purpose described.

2. In acetylene lighting apparatus the combination with a gas meter andburners, of two tube's communicating at one end with the gas meter andat the other wit-h the burners, means for regulating the passage of thegas through one of the tubes, two valve seats, parallel to and oppositeeach other and placed in the other of the said tubes, whereby said othertube is divided into two parts, the said valve seats being provided withports opposite each other and each communicating with one of the partsof said other tube, a rocker-valve adapted to move between and incontact with said valve seats, the said rocker-valve having a portadapted to be moved into and out of line with the ports in both valveseats simultaneously whereby communication between the two parts of thesaid other tube is opened, an arm rigidly secured to said rocker valve,a rod secured to said arm, a spring adapted to move said arm in onedirection, a wheel, teeth on the periphery oi said wheel and adapted toengage the free end of said rod, a gearing adapted to drive said wheelfrom the gas meter, a clock-work, and means for coupling the gas metershaft with one of the wheels of the clock-work, substantially as and forthe purpose described.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
